What i've done so far is seat the gas check, lube, and size with the .366" sizer to .3675" to .368". I then swap out sizer die to the .363" and swap out nose punches to the large 45 cal punch so it won't affect the GC then invert the bullet and size down to just the 1st lube grove, sizing the nose to .364". This is on bullets that have been sitting for several weeks, having had a chance to harden up to 15 BHN.
In the next few weeks, I'll perform the same procedure on freshly cast bullets with a BHN of 12, to see if the final dimension are more or less.
